The belts may be also provided, if required, with ribs (4) on the lower surface identical to the ribs (3) or different in form so as to 40 serve as impelling teeth for the belts. In this case the impelling pulleys (5) should be also provided with teeth (6) to correspond. This ensures the absolutely equal running of the belts so that the rods accumulated in the feeding funnel parallel to the shaft of the impelling pulley of the belts. The distance between the two conveyor belts depend on the article to be manufactured. Between the two belts (2) and at the same height there is located the belt ('7) Figs. 6 and 7 which may be of steel or other suitable material and moved by the pulley (8) is guided by the rollers (9). The roller (10) acts as a counterweight to keep an equal tension on the belt ('7), although any other tension system of known construction chine (11) :Fig. '8 of WhlCh'lSfjIJlOVidfid. with two or more holes for the'bolts (l3).

the drawings which accompany this specification 585 on which the type illustrated is only an example to show the method of working this new system, an emery belt (18) Fig. 8 is provided by the pulley (l9) and rollers (20). The pulley (l9) and rollers (20) aro locatedin the frame (21) which is bolted to the frame (ll) of the machine. Having described the different parts comprising the machine, the working of same is detailed below:

Working In the Figs. 6, '7 and 8 of the accompanying drawings the wooden articles (22) to be finished are shown as they are placed on the belts (2 and '7) below and with the pad (15) and emery belt (18) located above. The arrows indicate the direction in which the belts move. In order to have a better View of the different phases involved, we will imagine that there are only the two belts (2) which convey the wood (22), andthe pressure pad (15). As the wood is conveyed by the belts 2) and forced below the fixed pad, a similar occurrence, which may be observed daily, takes place when several labourers wish to move a I very heavy box and place a few rollers below it to facilitate the operation. In this invention the belts (2) represent the box and the. wood (22) represents the rollers while the pad (15) represents the fixed base. With reference to the box the power which is applied by the labourers when pushing and in our case the impulse given to the belts rotates the rollers, meaning in our case the wood (22) to be finished. This rotation produced by the conveyor belts (2) would be too slow to obtain efiicient work, so it is therefore necis to be finished has a circumference of 1 centimeter, the speed of the belt (2) equal to 100 centimeters per minute, the speed of the belt (7) 1.000 centimeters per minhas a length of 20 centimeters. Due to the velocity of the belt (2) the wood (22) requires 12 seconds to pass beneath the pad and must in that period of time make 20 revolutions. At the same time belt ('7) acts which would imply that the wood will only employ 1.2 seconds to travel underneath 20 centimeters of the pad making the same number of revolutions, but in our case the ribs (3) placed on the belt 2) prevent the wood rods of wood will be given, during the 12 seconds employed to travel the 20 centimeters of the pad-twenty revolutions impelled by the belt (2) and 200 revolutions impelled by the belt (7) a'total of 220 revolutions in 12 seconds or 1.100 revolutions per minute. In front of the pad (15) smooth. The modifications which may be made to the cutting, smoothing and polishing devices or tion, neither are its activities to be confined to wood work as it can also be successfully operated with bones as well as with metals.

Following the example shown in the accompanying drawings we find that the work to be done consists in the smoothing of the central portion of the wood (22) the width of which corresponds to that of the belt (7). As illustrated in Fig. 8 the emery belt (18) only smooths half of the piece of wood and it is therefore necessary to install identical finishing and pressure devices but in inverted form on the same length of travel of belt (7) as illustrated in Fig. 2. In this manreceive them or if' conveyor belt. a
